(1) The embodiments of the inventions described herein will be better understood from the following detailed description with reference to the drawings, which are not necessarily drawn to scale and in which:

DETAILED DESCRIPTION

(5) FIG. 1 illustrates a cross section of an embodiment of a low-cost balance exerciser 100 for use at work. An exemplary embodiment of the balance exerciser 100 includes a base 103, upon which a central support 112 for a ball joint 109 and an inflatable elastic toroidal bladder 106 are disposed. The inflatable elastic toroidal bladder 106 is centered about the central support 112 and the ball joint 109. The ball joint 109 is fixed to the underside of a rigid circular balance platform 115 at its center and the elastic toroidal bladder is sandwiched between the underside of the rigid circular balance platform 115 and the base 103. The diameter of the balance platform 115 is greater than that of the outer diameter of the inflatable elastic toroidal bladder 106 and has a peripheral edge that extends down beyond the central bottom surface of the balance platform 115.

(6) The ball joint 109 allows the rigid circular balance platform 115 to tilt in any direction of the horizontal x-y plane. The user's center of gravity relative to the center of the balance platform 115 and the inflation pressure of the inflatable elastic toroidal bladder 106 determine the direction of tilt of the balance platform 115 in any of the 360 of the x-y plane and the magnitude of tilt of the balance platform 115 along the z-axis, which is generally measured in angular degrees. While standing on the balance platform 115, forward and backward or side-to-side movements by the user cause the user's center of gravity to shift, resulting in corresponding changes in direction and magnitude of tilt for the balance platform 115.

(7) In an exemplary embodiment of the invention, when the inflatable elastic toroidal bladder 106 is inflated to a maximum pressure, the balance platform 115 is relatively stable and large movements by the user result in only small changes in the magnitude of tilt. However, when the inflatable elastic toroidal bladder 106 is inflated to less than maximum pressure, the balance platform 115 is less stable and smaller movements by the user result in comparatively larger changes in the magnitude of tilt. In an exemplary embodiments, the maximum downward tilt of the balance platform 115 along the z-axis in any direction of the horizontal x-y plane may preferably be limited to less than or equal to 20 by a section of the peripheral edge of the balance platform 115 that touches the ground at the maximum downward tilt. More preferably, the maximum downward tilt by the balance platform 115 in any direction of the horizontal x-y plane may be limited to less than or equal to 15. Of course, a downward tilt in one direction of the horizontal x-y plane by the balance platform 115 results in an equal upward tilt of the opposite side of the balance platform 115 about its center.

(8) Referring to FIG. 1, a pump 118 inflates the inflatable elastic toroidal bladder 106 of the balance exerciser 100 in an exemplary embodiment of the invention. In various embodiments, the pump 118 may include any one of: an air stand pump, an air hand pump, an air foot pump, and an air electric pump. The pump 118 may include a flow control valve 121, to control the flow and pressure of the inflating air to the inflatable elastic toroidal bladder 106, and a ball check valve 124, to release or maintain the pressure. In an exemplary embodiment, inflating air may travel from the pump 118 through the flow control valve 121 to an air hose 127 that may connect to a pressure gauge 133 and to an air line 130, which connects to the inflatable elastic toroidal bladder 106.

(9) Alternatively, a valve stem may (not shown) may be connected to the air line 130, which connects to the inflatable toroidal bladder 106. The pump 118 may then be connected to the valve stem to inflate the inflatable toroidal bladder 106. The inflatable toroidal bladder 106 may be deflated by disconnecting the air hose 127 from the valve stem and the stem of the valve stem deflected sideways to allow air to escape from the inflatable toroidal bladder 106.

(10) In an exemplary embodiment, the pressure gauge 133 may be attached to an upper surface of the balance platform 115. The pressure gauge 133 may indicate a pressure of the inflatable elastic toroidal bladder 106 ranging from, for example, a minimum pressure of 0 pounds per square inch (psi) to a maximum pressure of 20 psi. The pressure gauge 133 may be connected directly or indirectly to the inflatable elastic toroidal bladder 106. Alternatively, the external pump 118 may include a pressure gauge (dotted circle) that indicates the pressure of the inflatable elastic toroidal bladder 106.

(11) In another exemplary embodiment of the invention, adjustable leveling feet 136 may be positioned on the bottom surface of the base 103 of the balance exerciser 100. Preferably, four adjustable leveling feet 136 are positioned in a quadrilateral pattern to allow leveling relative to forward, backward, left and right directions. A bubble level indicator 139 may extend laterally from the base 103, so that the user may readily determine a level of the balance exerciser 100. As shown in FIG. 2, each adjustable leveling foot 136 may include a foot 242 and a threaded stud 245 that is advanced into or retracted from a corresponding threaded hole (not shown) in the base 103 of the balance exerciser 100.

(12) Referring to FIG. 3, adjusting the level of the base 103 of the balance exerciser is facilitated by the bubble level indicator 139, a support 348 for which extends laterally from the base 103 and which may include marks 351 indicating forward, backward, left, and right directions of tilt and a circular mark 354 indicating a pre-defined magnitude of tilt in any of the 360 of direction relative to the ground in an exemplary embodiment of the invention. For example, the bubble 357 may indicate the balance exerciser 100 is tilted forward by 5.
